  35 /* On some, not all, sun4's SunOS4.0.3 there is a bug in strtod().
  36    strtod("0",0) sets errno to ERANGE sometimes! which announces
  37    underflow which is not true.
  38
  39    If you get strange error messages:
  40
  41    mawk: line xx: 0 : decimal underflow
  42
  43    then your strtod() is broken and use this file as config.h
  44
  45    Otherwise use generic.h as config.h.
  46
  47    I've talked to Sun and they tell me its a known bug thats
  48    fixed in 4.1
  49
  50    ----------------
  51    It can happen on sun3's too. (8/23)
